  The SAP error message CNV10310557 indicates that there is an overlap of structure fields in the context of a data conversion or migration process. This typically occurs when two or more fields in a structure are defined in such a way that their memory allocation overlaps, which can lead to data corruption or unexpected behavior.
  Cause:
  
  
  Field Overlap: The error arises when the fields in a structure are defined with overlapping memory addresses. This can happen if:
  
  The fields are defined with incorrect lengths.
  The fields are not properly aligned.
  There are changes in the structure that have not been properly managed.
  
  
  
  Data Migration Issues: This error often occurs during data migration processes where the source and target structures do not match correctly, leading to conflicts in field definitions.

  Check Data Mapping: If this error occurs during a data migration process, review the mapping of fields between the source and target structures. Ensure that the mapping is correct and that there are no conflicts.
